I am looking for the best combo of performance and induction noise, I am not interested in how it looks
Fair enough, some of the best sounding systems don;t fit the LCR e.g. Carbonio as the LCR has a second intercooler and this blocks the route they use.
Performance wise these kits add a few BHP if your lucky but in my opinion they are worth it for the sound alone.
The three I named above are all good and probably isn;t much in it perfomrnace wise (I tried all 3)
RAM AIR - Great Sound but Build is not the Best
Dynatwist - Probably the best / sound and performance compromise
Both of the above are avialable from Bill at Badger 5
The Steve Schwing TTDA system recommended by Owen also looks good but you need to ship it from the US yourself
